WEBER, OF EVANSVILLE, INDIANA HARDWARE FOR REVOLVING DOORS Application led July 22, 1931. Serial No. 552,496.

My invention relates broadly to revolving doors and more particularly to hardware for revolving doors arranged to permit the collapsing of the doors under excess pressure :s directed against the doors.

One' of the objects of my invention is to provide a simplified construction of hardware for revolving doors having a minimum number of parts assembled in such manner r that the hardware may be manufactured inexpensively on a quantity production scale.

Another object of my invention is to provide a construction of collapsible hinge for revolving doors whereby sets of revolving doors may be normally maintained in 90 relationship and und-er emergency conditions may be independently moved to a collapsed position in which the doors extend parallel to each other.

Still another object of my invention is to provide a construction of hinOe for revolving doors having means for supporting the individual doors of the revolving door system in such manner that independent move- Z ment may be imparted to any one of the doors for moving the individual doors to different angular distances around a multiplicity of dilerent pivots for shifting the doors under emergency conditions from poilu sitions normal to each other to collapsed positions parallel to each other.

A further object of my invention is to provide a. construction of hardware for revolving doors in the form of disc members disl posed adjacent the top and bottom of the i'evolvable shaft of a rotating door system where the discs have yoke members pivotally mounted therein in symmetrical relation, each of the yoke members having wing carriers pivoted therein for mounting the separate doors, the yoke members and wing carriers each having' different paths of movement when shifted to different angular positions for allowng ak collapsing of the several doors into parallel position under condit-ions of excess pressure exerted against the doors.

A still further object of my invention is n to provide a simpliied construction of hardware for revolving doors wherefn discs ixed to the revolving shaft of a door each supportyoke members pivoted in symmetrical arrangement therein with wing carriers shifted to embrace the yoke members and pivoted with respect to the opposite extremities of l the yo-lres so that the wing carriers may be l moved in alignment with the yokes throughout an angular distance of approximately 45o about the pivot between the yoke and the supporting disc and thereafter disengaged from alignment with the yoke and independently moved through a distance approximately 90o whereby the several doors may be shifted from normal position to a position in which the doors are aligned in parallel arrangement.

A further object of mv invention is to provide a construction of hardware for revolving doors in which a pair of hinge members may be disposed in horizontal planes adjacent the top and bottom of the door system and positively spaced by means of atubular member extending between the hardware and concentrically disposed about the shaft which carries-the several doors.

Other and further objects of my invention will be understood from the specification hereinafter following by reference to the accompanying drawings, wherein:

Referring to the drawings in detail reference character 1 designates the vertically disposed shaft which carries the revolvable door, adjacentV the top and bottom of the movable door, on which I arrange the hardware shown in the drawings. The hardware supports the several wings in predetermined relation as illustrated. In order to attach the hardware to the wings I provide means eX- tending from each of thewing supports and providing a socket through which the shaft extends. The sockets on the hardware members vare attached to the 4shaft by any suitable means such as screws ext-ending radially through the sockets and engaging the vertically disposed shaft. In between the two hardware` members there is a tubular shield which extends over the shaft and provides longitudinally extending pockets into which the edges of the wings of the door t. Each hardware member is provided with four leaf hangers which arer adapted to be locked in 90 relationship foi,` maintaining the wings in operative position when the door is revolved. The leaf hangersn however are arranged so that they may be collapsed in parallel relation under abnormal pressure against the wings of the revolving door.

Each of Vthe hardware members comprises a disc member 2 aperturedl at its center at 8 for the passage of theshaft 1. The disc- 2 is preformed as shown in the planview to enable the leaf hangers to be angularly shifted through an angular distance as large as 135 in collapsing the doors to a-safety position under conditions of abnormal pres- The sockets 4 by which the disc 2 is secured rigidly to the shaft 1 is eXteriorly formed with arcuate shaped faces designated at 5 in diametrically opposed positions` with arcuate shaped faces v being spaced one from another by intermediate ribs 6. The arcuate shaped faces 5 are formed on a radius r extending from the center7 in the discv2. The screws 8 which pass j through the socket 4 engage sc rewV threaded apertures in the shaftA 1 for locating the disc in position with respect to the shaft 1. The discs 2 are mounted adjacent the top and bottom ofshaft 1 and positively spaced by-tubularmeniber 27 which extends therebetween.` The centers 7 are utilized as pivot points for the hinged yokes v9. There-are four of these hinged yokes 9 which are angularly movable about centers 7 in the disc 2. Each yoke 9 has leg portions which embrace opnosite sides of the disc 2 and an end portion 9a which provides a pivot means 11 for the wing 10 of the revolving door. The portion 9a of the yoke 9 has a plunger 12 mounted therein under control of thespring 13 which tends to continuously urge yscribed in more detail.

the plunger 12 radially inward for engaging sockets 14, 15 and 16 in the faces of the disc iii predetermined angular positions in the edge of the disc 2 for maintaining the wing of the door in a predetermined angular position. That is to say, the several positions of the plunger with respect to the. sockets enable the wings to be maintained in normal position or collapsed in either of two different directions as will be hereinafter derIhe intermediate portions 17 of the disc 2 provide eXtreme limit stops for the yoke 9 in either of the extreme positions thereof. In order to shape the lisc 2 to provide for the adjusting positions for the wings and the opposite limit stops, the disc 2 has its periphery formedon a radius rfrom the center 7 and the stopsA 18 and 19 having their faces extending radially from the center 7. y

The wings are mounted uniformly about the disc in each of the leaf hangers. Intheir normal position where the leaves are disposed at 90 with respect to each other, the leaves are secured in the radial position shown in the drawings with plunger 12.en`- tering socket 15. The wings while maintained iii their normal position at 90 with respect to each other are readily collapsible under abnormal pressure. rI`he immediately adjacent wings are collapsedtoward each other from a position of 90 separation to a position yhere the wings extend parallel one with respect to another. This is accomplishedby merely shifting the yokes about the pivots 7 and moving the plunger or detent 12 out ofthecenter socket 15 and into the inner sockets 14 and 16, respectively. In bringing about this motion the inner edge of the leaf hangers 20 are free to move with respect to asinuch as the edges of the leaf hangers 20 are formed on the same radius as the radius of the arcuate shaped faces 5 about the pivot point 7 of the yoke 9 as a center. The wings 21 and 22 which are moved into a parallel position adjacent 'each other are shifted so that the yokes 9 are moved in alignment with the leaf hangers 20. This alignment must be maintained in order to shift the wings 21 and 22 toa parallel position. The collapsing of the wings 21 and 22 is broughtabout by inI ward pressure upon the wings 21 and 22V tol ward each other, the yokes 9 pivoting about the pivot 7 asa center and allowing the interior edges of both yoke and wing-hanger to pass in a predetermined path around the arcuate shaped face 5 on pivot 7 as a center.

With respect to wings 24 and 25, it is first necessary to rock the wing hangers in align ment with the yokes about pivots 7 as a center and thereafter the wing hangers are independently moved about the pivots 11 as a center on a radius R- for shifting the wings 24 and 25 to the parallel position shown in collapsed position. This is l. diagrammatically :which may take many different forms and Fig. 4. That is to say, the wing hangers are firstmoved in alignment with the yokes 9 and thereafter disengaged from alignment with yokes 9 and given an independent movement allowing the four wings to have the same direction inv collapsed position toward the pointof egress from the building.

It will be observed that the pivots 11 eX- tend through the wing hangers and into the sockets on each side of the yokes 9 as represented at 11o; and 11K. The doors may be collapsed in either direction. IV hen a direction of collapse opposite to the direction illustrated is required then the wings Pil-and are moved to a parallel position. In bringing about this movement the wing hangers 2O have an inward pressure applied thereto which serves to shift the wing hangers in aligned position with the yokes 9 from a position secured by detent 12 in socket 15 to a position where detent 12 enters socket 16 and 1-1 respectively, the yokes and wing hangers moving about pivot- 7 as a center. t is then necessary to bring the opposite wings into accomplished by first moving the wing hangers and yokes in aligned position until the point of disengagement is reached, whereupon the wing hangers have independent movement about .f pivots 11 as a center allowing the wings to move through a further angle of 90o in assuming a position where the doors are col lapsed in parallel arrangement in a direction opposite to the direction illustrated in -It will be api reciated that under emergency conditions the revolving door may' be in any angular position so that the collapsing operation-heretofore described is not only possible in the two directions described but shown in Fig. 9 which can be released under abnormal pressure, which cables have been illustrated herein but which may be secured by a great ferent structures of cable locks.

`F1g. 8 shows the arrangement of the hardnany difware wherein the socket portion of each hardware member is directed toward the top and bottom of the wings constituting the doors. The hardware is positively spaced by means of the tubular member 27 which is concentrically disposed about the tubular shaft 1. The tubular member 27 bears directly against the faces of the discs 2 which are opposite the faeesof the discs 2 which carry the socket 4 and thus provides a positive means for spac- .ing the discs 2 on the shaft 1 in addition to the securing means 8 which are used to fasten the sockets 4 to the shaft 1.

The structure of my invention has many advantages over the prior principles among which I may mention the simplicity of the design herein and thev capability of quantity production inexpensively. The number of parts in the structure of my invention has been reduced to a minimum as compared with complicated structures -embodying gears and ratchet members heretofore employed in the One of the principle advantages of my invention resides in the method by which the wing hangers is secured in position with respect to the yoke which connects with the supporting disc. Alignment of the yoke and the leaf hanger is automatically maintained through a displacement of and then disengagement automatically brought about to permit movement of the wing through aV further angle of 90 to the collapsed position of the wings.

I have found the construction of hardware according to my invention highly practical and while I have described one of the preferred embodiments of my invention I desire that it be understood that modifications may be made and that no limitations upon my invention are intended other than are imposed by the scope of the appended claims.
